Hello
Thanks for the report. I have never seen this issue. I have CentOS 7 VMs
(kvm), lstopo works fine. Did you try this in similar VMs in the past?
When you say "latest hwloc", do you mean "build latest tarball" (1.11.2)
or "installed latest centos package" (1.7)?
First thing to check: run
Hi Brice
Thanks for the reply.
I use yum install hwloc to install it.
The cpu usage is 100%.
I got this after Ctrl + C, and c, several times:
0x77bce13c in look_proc () from /lib64/libhwloc.so.5
Always the same place.

I just realize that yum on centos 7 use hwloc version 1.7.
I Downloaded 1.11.2 version source, built and install. Still hangs.

I did a debug build. Found it loops forever in this loop in
topology-x86.c:404.
